WILLIAM DOYLE, or ALBANY, NEW YORKI IMPROVEMEN I' IN PARLOR COOK-STOVES'.

Specification forming part of Letters "Patent No. 165,920, dated July27, 1871' application filed May 31, 1875.

CASE B.

To all whom it may concern:

Be it known that I, WILLIAM DOYLE, of the city and county of Albany,State of New York, have invented certain Improvements in ParlorOook-Stoves; and I do hereby declare that the following is a descriptionthereof, reference being had to the accompanying drawings in two sheets,forming a part of this specification, in which Figure 1 represents asectional elevation, taken from front to rear, illustrating theimprovements in this invention. Fig. 2 is a sectional elevation in thetransverse, taken at line No. l in Fig. 1. Fig. 3 is a plan view of thebase, taken at lineNo. l in Fig. 1. Fig.4 is a plan view at line No. 2,Fig. 1. Fig. 5 is a plan view at line No. 3, Fig. 1. Fig.6 is a planview at line No. 4, Fig. 1. Figs. 7 and 8 are plan views of thering-damper, illustrating the same variously set for differentoperations.

My invention relates to parlor cook-stoves having an oven and pot holeor holes located at the rear side of the stove proper; and con' sists ofthe several devices or parts and their combinations, hereinafterdescribed, whereby the heating-stove proper may be employed for warminga room without materially effect ing a heating of the oven; 'or the ovenmay be highly heated for baking purposes without the stove properbecoming highly heated; or a vessel placed on the pot-hole may beoperated with for boiling, frying, or broiling without the oven or withthe same in operation, or with the stove proper operating to warm atroom; or the several parts may be simultaneously heated for warming,baking, or other cooking purposes.

To enable others skilled in the art to make and use my invention, I willproceed to describe it in reference to the drawings and letters ofreference marked thereon, the same letters indicating similar parts.

In the drawings, A represents the basesection of the stove. B is thefire-pot and ash-pan section. 0 is the combustion-chamber section. D isthe reservoir-section, and together the said several sections form thestove proper for warming purposes, which may be made with any desiredform of outline and ornamentations. The base-section Ais made with anextension, A, as in a former invention secured to me by Letters Patent,and has placed over it the oven E, located at the rear of the fire-potF, and about on a plane in its top portion with the top of the saidfire-pot. The stove proper is provided with side flues a a, one or moreon a side between the outer casing andthe fire-pot, and leading into thebase through the lines b b to the central flue c. The said central fluedis charges into the flue cl below the oven, and may be opened or closedto the same by the damper 6, Figs. 1 and 3. Over the oven is made thehorizontal flue or chamber f, and at the rear the descending flue g,which flue is extended around to one sideof the oven, and

forms an angle, g, of the said descending flue, as shown. The saiddescending flue g g communicates from the top flue f to the rearhorizontal flue h beneath the oven. A flue-strip, i, separates the saidrear horizontal flue h from the front horizontal flue d, and acommunication is had from the former to the latter flue through theopening 0, Figs. 2 and 3, Leading from the horizontal flue d at a sideof the oven, and adjoining the angle g of the descending flue, andseparated by the fluestrip k, is the side ascending flue m, whichascending flue communicates with the larger ascending flue M at the rearof the combustion-chamber, and leads to the exit a. Leadingfrom thecombustion-chamber O of the stove proper into the top horizontal flue orchamber f is the top flue q, the side walls of which on one side areformed by the wall of the casing of the stove, and on the other side bythe plate 4", while the top wall is formed by the plate 8, as shown inFig. 2. The said top flue being thus formed is located at the base ofthe ascending flue M, and is adjoining to the same at its bottom andside, as

shown, so that the hot gases passing fromthe combustion-ohamber G to thetop horizontal flue will highly heat the plates 1 ands,

and thereby highly heat theascending flue at a point a little below theexit .n, and thereby stimulate the draft of the stove "by highlyrarefying the gases ascending in the enlarged flue M, just below theexit. The pot-hole t made in the top plate of the flue f is providedwith a ring, a, Figs. 1, 5, 7, and 8, carrying a damper, t, which may beset to any desired position, as shown by full and dotted lines in thesaid figures.

1n operating with this improved stove for the several purposes intended,the several directions of draft of the hot gaseous products ofcombustion from the combustion-chamber to the exit may be regulated bythe ringdamper a c and base-damper e.

To direct the hot gases into the base of the stove proper to heat thesame for warming rooms, the damper e is to be turned open, as in Figs. 1and 3, and the ring-damper is to be turned to the position shown bydotted lines in Fig. 5 and full lines in Fig. 8, to close the opening mto the ascending flue M, when the hot gaseous products will be made topass from the combustion-chamber 0 down the side flues a a into thebaseflues b b and c thence into the horizontal flue d for passage to theascending flue m, and up said ascending flue to the more extensiveascending flue M, and from the same through the exit a, as indicated byarrows No. 1 in Figs. 1, 2, 3, and 4. I

When it is desired to heat the oven only, anddivert all the hot gasesfrom the base of the stove proper, the base-damper e is to be turnedclosed, as shown by dotted lines in Fig. 1, and the ring-damper is to beset, as shown in Fig.8, to close the opening m to the ascending flue M,when the hot gases may be made to pass from the combustion chamber 0through the top flue q (and highly heat the bottom of the said ascendingflue, and thereby increase its draft by stimulation by heat) into thehorizontal flue or chamber f thence down the descending flues g 9 intothe lower horizontal flue h, and from thence pass through the opening 0into the horizontal flue d, and from the same into the side ascendingflue m, and upward from the same into the flue M to the exit a, asindicated by arrows 2 in Figs. 1, 3, 5, and 8, in which passage the hotgases drawn from the combustion-chamber will heat the oven and topplate, and not the base of the stove proper.

- YVhen it is desired to heat the top plate of the horizontal flue orchamber f, and any vesselsitting in the pot hole or holes, the ring a isto be turned so as to carry the damper-plate c from the opening m to theascending flue to any desired position, as shown in Fig. 7 by full ordotted lines, or to any other position that will open a communicationfrom the chamber f to the base of the enlarged ascending flue M, whenthe hot gases will pass in-the direction indicated by arrows 3 in Figs.2, 5, and 7.

When it is desired to cause a portion of the hot gases to descend intothe base of the stove proper, and another portion to pass around theoven, the damper e is to be opened, as in Fig. 1, and the ring-damper isto be turned so as to partially close the opening m to the ascendingflue M, in which case the draft will cause the hot gases to be dividedin their volume. into two currents, one moving substantially asindicated by arrows 1, and the other as indicated by arrows 2.

When the damper in the base is closed, and the ring-damper. is set topartially close the opening m to the ascending flue M, one portion ofthe hot gases will be made to pass around the oven, as indicated byarrows 2, and another portion will be made to pass direct from thechamber f to the ascending flue M, as indicated by arrows 3, while thebase of the stove proper will be slightly heated.

It is evident that by these improvements the stove is rendered capableof a variety of operations with the heat generated by the combustion ofthe fuel, so as to be in readiness at all times for warming rooms,baking, or roasting, or for boiling, broiling, frying, and otherprocesses in cooking, and is rendered advantageous for either winter orsummer use.

It is to be understood that I do not confine my improvements to stoveshaving a small oven and a single pot-hole, as it is evident that theoven may be enlarged and the number of potholes may be increased torender the stove capable of being employed in large families for generalcooking as well as for heating purposes.

.Having described my invention, what I claim, and desire to secure byLetters Patent, 1s
